others remember when union supporter martin luther king, seen here, marched with one of america's most accomplished labor leaders, walter ruther, seen here with his hand on king's arm. >> you're young, aren't you? ruther. >> today's protests are reminiscent of an eight decade old fight. in the coming months, that fight could turn into a citizens initiative, repeal, lawsuits or even a recall of elected officials. michigan's law goes into effect in a little over three months. >> do we have any indication because obviously this is a movement, which states might be next? >> take a look at michigan, seen as the center of the labor movement. even the top four union members states could be at risk. at the top you have new york with one in four workers a union member, followed by alaska, hawaii and washington. the number you see on the screen right here, which is the advocacy money, that could be what's changing these traditional union states. according to the nation, we look at those numbers from 2008 to 2011, right to work money was $18 million. pro-union, just $2 million. >> thanks so much.
